Sanitiser dispenser

Tävlingssammandrag

I have designed a wall-mounted, handsfree sanitiser dispenser for domestic homes' point of entry - ie front or backdoor. It will be a 500ml refillable unit containing a sanitiser with a gel and alcohol make-up. I want to find and test a system that
1) infra-red sensor that sprays a 1-1.5 ml jet of sanitiser when hand passes approx 3-5 inches beneath.
2) valves that snap shut tightly to prevent messy drips onto floor surfaces. I am particularly interested in the quality of this element (perhaps silicon - I am inspired by the Simplehuman new technology automatic soap-dispenser as product is aimed at high end homes with expensive floor surfaces and also the alcohol in the sanitiser could potentially stain, and in worst case scenarios cause a fire.
3) an efficient pump,
4) low power consumption or rechargeable batteries
5) best value and best suited PCB
I need an electrical engineer to advise on sourcing. give me a BoM for the electrical components, so that I can optimise the efficiency and productivity of my dispenser. If you are interested, can you give me a time-frame for delivery

    Hello,
    I have seen the simple human's mechanism would you like a similar system? I designed two products one dispensing from bottom and other from the top. But I saw you mentioned you have your own design. Could you add pictures? or describe your design to decide which approach is better for your design
